I haven't seen it talked about (as there seems to be only a little discussion of it on here so far) but one of the things I love love love about The Residence is that she gives up on the investigation.
Cordelia Cupp, world's best detective, who solves the unsolvable, gives up... because she prioritizes the reputation and livelihood of a man she respects and who respects and supports her in turn. Chief Dokes knows that continuing to pursue the case will mean the end of his career, but he says nothing... until she asks. She asks. She knows that there are consequences to her dogged pursuit of the truth, she asks about them, and despite the fact that Chief Dokes is willing to accept those consequences, she says "I'm not."
In a genre that is often characterized by detectives who keep pursuing the case to the ends of the earth - consequences and fallout be damned - I am desperately in love with this character who is blunt and clever and justifiably arrogant and still shows such compassion to those who support her to say "I will not ask this price of you, even if you're willing to pay it, because what you built your life around is not more important than finding my answer."
We have multiple anecdotes through the series about her obsessiveness and indefatigable pursuit of her goals and unwillingness to give up until they're achieved, and yet she will not throw over Chief Dokes for the sake of seeing this thing through.
